Description:
This pull request includes improvements to error handling in
mode.go
andfs.go
:SetMode function in
mode.go
: Previously, the SetMode function would panic when an unknown mode was provided. This behavior has been modified to return an error instead of causing a panic, allowing for more graceful error handling. The corresponding tests have also been updated to reflect this change.Open function in
fs.go
: The error message returned when opening a file has been enhanced to provide better context, similar to the error handling in Python.These changes aim to improve the robustness of the code and provide clearer, more informative error messages to users.
